Same deal as with that Bundy/Overpass standoff between militia types and the Feds a few years ago. The Feds showed up, saw the number of men with rifles, turned around and went home. Mission accomplished right? The militia guys all pat each other on the back and congratulate themselves on scaring off the feds. Except they then get quietly arrested one by one over the next few months. Those arrests never become big headline stories like the initial standoff, so you still have fools today who think those standoff tactics are viable.
